Application led September 26, 1919. Serial No. 326,596*` To all whom t may Concern.'

Be it known that I, VILLIAM J. Hosonrr, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsv in a General Service Car, of which the following is a specication.

This invention relates to general service cars, and more particularly to the frame and door construction thereof.

General servicecars to be of the greatest utility should have the ioors thereof formed substantially wholly of doors. It is simple enough to provide floor doors between the trucks and at the same time make the car frame suihciently strong to overcome buing and racking strainsto which the frame is subject, but, in addition, to provide Hoor doors over the trucks and make. the frame sufficiently strong, and at the same time relatively light, is a problem of considerable ma 7nitudel ne object of my present invention is to construct a general service car having floor doors throughoutits length and at the same time make the car frame strong enough in construction to overcome the `buhng and racking strains to which the same is sub. jected, the weight of the frame beingmaintained at a minimum. y

Another object is to provide a general service car simply and novelly constructed and adapted to meet the various requirements of service conditions.

These and other objects are accomplished by means of the car construction shown on the accompanying sheets of drawings, inV

which v Figure 1 is a fragmentary side elevation of a general service car embodying my invention; and,

Figure 2 is a transverse sectional view of the same car taken over the trucks and in the plane of line 2 2 of Figure 1.

Referring to the figures of the drawings, it will be noted that this general service car includes sides 10, ends 11 and a floor, the longitudinal centra-l portion 12 of which is flat and is supported over the center sills 13. The floor is formed substantially whollyof doors throughout its entire length, the doors being arranged on opposite sides Of the center sill, and when in closed position being on the same level, or substantially so, with the floor portion 12. Not only do they oordooi's i 14 extend between the trucks, but they are also arranged over the trucks.` As shown in Figure 2 of the drawings, vitV willbey noted that the floor doors 14 are pivotally mounted at 15 along their inner ends on' opposite sides of the centersill. These doors' 14 are arranged to dump the loadv to the sides'of the car. As viewedfin Figure 2, the floor door 14 at the left-hand side is in closed position, and is held in such position by a lsupporting and operating shaft 16, which carries a,plu rality of gears 17 each of which meshes with a cooperating rack 18 formed in a bracket 19 carried by the body bolster 20 and other Vtransverse frame members, said bolster rand transverse frame member each being .provided with a slot 21 whereby` the shaft may move laterally inwardly and outwardly. As shown at the left-hand side of `Figure 2, :the

shaft 16 occupiesthe innermost end of the slot 21 for holdingthe floor doors 14- in. raised or closed position. To *permit the floor doors 14 to swing downwardly Lintoan open position for dumping purposes, the

shaft 16 is movedl laterally outwardly to the outer endof the slot 21, whereupon; the doors 14 are free to drop into open'` position, as shown in the righthand side of Figurel 2., The shaft 16 in each case may be operated by any suitable handle 22, which in. this ease is angular in shape to pass aroundthe lower edges of the car, the handle beingheld in" its raised position by any suitable means `23; As mentioned hereinabove, itfis a: sim-ple matter to make the frame construction ficiently strong to lovercome buiiing and racking strains when floor doors are. used, only between the trucks, but a difiicult prob lem is `presented when, in addition, Hoor doors are provided over 'the trucks. i

if there are a large number'fof Hoor doors,

Even though a car frame may be relatively rigid,v

the frame soon will be skewed and forced` out of shape imder service conditions.,` uuless a special construction is provided. This is especially so in the present case where notr only floor doors are used between the trucks, but where floor doors additionally are pro# vided over the truc-ks. To overcome these b-uffing and racking strains and to stiffenthe frame of the car at the vital points, I have providedlongitudinally extending rigid re"- inforcing frame members or plates 24 which extend between and are rigidly connected to i tion toward the sides of the car.

the body bolster 20 and end sill 25 at the ends of the car. The rigid plate 24 at each end of the car is bent, the top portion thereof being mounted upon and over the center sill 13 and intermediate the latter and the floor late 12. The inclined side portions. of the plate 24 extend from the top of the center sill in a. downwardly and outwardly direc- The inclined portions of the plate 24 are located on either side of the center sill intermediate the latter and the sides of the car. These rigid A-shaped plates 24 at each end cover a considerable distance transversely of the car. They also form stops for the floor doors 14 over the trucks and also support the brackets 26 to which the doors 14 are pivoted.

By means of this. construction the floor of the car may be formed substantially wholly of doors throughout its entire length and including floor doors over the trucks, the car frame at the same time being properly constructed to overcome the buing and racking strains encountered under service conditions.

It is my intention to cover all modifications of the invention falling within the spiritand scope of the following claims.

I claim: i

l. A general service car having sides, ends and a floor, the latter being formed substantially wholly of doors; throughout its length and including Hoor doors over the trucks, and rigid frame members extending between an end sill and body bolster for strengthening the frame and also serving as a stop for an associated door; the frame members diagonally ofthe depth of the body bolster and end sill and Within their contour.

2. Av general service car having sides, center sills, ends and a Hoor, the latter being formed substantially o-f doors throughout its length andy including floor doors over the trucks, and inclined reinforcing members extending from a point adjacent the top o-f the center sill downwardly and outwardly wardly and outwardly toward the sides of the car and being secured to an end sill and bolster the end sills and bolster being adjacent the center sills substantially of equal depth with the center sills.

4. A general service car having an underframe comprising a center sill and cross members extending from the center sill toward the sides of the car, a substantially horizontal floor from end to end of the. car composed largely of dro-p doors hinged at or near` the center sill, and rigid frame members below the floor on either side of tne Center sill extending between the end sills and body bolsters and connected thereto, said end sills and body bolsters being equal in depth to the center sills.V l

5. A general service car having an underframe comprising a center sill and cross members extending from the center sill to ward the sides of the car forming rectangular openings, a substantially horizontal floor extending from end to end of the car comprising doors hinged at or near the center sill, said doorsilling said openingslwhen in closed position, and rigid inclined frame members below the floor at the ends of the car, said members extending between the end sills and body holsters and being connected thereto, said end sills and body bolsters beino equal in depth to the center sills.

bigned at Chicago, Illinois, this 23rd day of September, 1919.
